I can’t speak for other tube amps, but there is no recommended service interval for these. Replace the tubes when they burn out, and repair things as they break (as with anything else). I’ve had this amp 16 years now, and I’m still running the original tubes. They’ll likely need to be replaced soon, but that’s not a bad run

Damn! That is really good, when I was looking at amps I kept seeing people talk about the tubes and other components need to be replaced after 5-10 years. Wonder if the high price point helps with better quality.

From what I understand, amp design can have a pretty significant impact on tube life. The harder the tubes are driven, the more often they’ll need replacement, so the amp tubes (the large 4) will need to be replaced probably twice as often as the pre-stage (the smaller ones in front). Considering this only puts out 75 watts per channel, it’s a pretty conservative design.
